boolean ec_configdc ( void )

Locate DC slaves, measure propagation delays.

Set DC's of all slaves to sync with the first, measure propagation delays.

return boolean if slaves are found with DC

Here is the call graph for this function:

Here is the caller graph for this function:

Set DC of slave to fire sync0 at CyclTime interval with CyclShift offset.

Parameters:

`[in]`	slave	Slave number.
`[in]`	act	TRUE = active, FALSE = deactivated
`[in]`	CyclTime	Cycltime in ns.
`[in]`	CyclShift	CyclShift in ns.

Here is the call graph for this function:

Here is the caller graph for this function:

Set DC of slave to fire sync0 and sync1 at CyclTime interval with CyclShift offset.

Parameters:

`[in]`	slave	Slave number.
`[in]`	act	TRUE = active, FALSE = deactivated
`[in]`	CyclTime0	Cycltime SYNC0 in ns.
`[in]`	CyclTime1	Cycltime SYNC1 in ns. This time is a delta time in relation to the SYNC0 fire. If CylcTime1 = 0 then SYNC1 fires a the same time as SYNC0.
`[in]`	CyclShift	CyclShift in ns.
